Dev builds an MCP server that lets Claude auto-generate DraftKings and FanDuel lineups
dfsstudio · reddit · 2026-11-15
A daily fantasy player, tired of clicking through optimizers before lock, built an MCP server so Claude does it all: say "build 20 NBA lineups for the main slate, lock Jokic, nobody over 40%" and it generates lineups, sims them against your contest, and fills the entries CSV. If a player is ruled out after lock, one prompt swaps him across every affected entry. The free version needs no account or key — add it as a custom connector at dfs.studio/mcp/free for tonight's slates, optimal lineups and top plays. Two practical takeaways: making every error message tell the agent exactly what to send next mostly eliminated failed tool loops, and a single myday tool answering "what should I look at right now" helped more than any prompt tweak. Most of the code was written by Claude Code.
